Indeed, when was the last time you saw an image in TARGA format? This plagues engineering greatly too. Back in the 90s there was a big push to do everything with CAD/CAE/CAM. But no one product had staying power, and there were few, if any, common digital formats for design data. So even after some firm upgraded to a new system, instances of old computer systems had to be kept and maintained in order to access the old stored designs. Even at the time the space shuttles were retired, there was no definitive external record of any of the orbiters. Each contractor and subcontractor had its own digital record in its own format It remained the case that if you really needed to confirm exactly how something was built on the orbiter, you had to go and physically inspect the orbiter.
